broadband Gigafast

I have been getting Gigafast since sept but when I do a speed test

at fast.com it says that I am getting just 94Mbps can anyone help me

because Sky cannot work out what is wrong (I even had an engineer come

out and even he could not work out why this was happening

@davidoakley55

Is that over Cat5e ethernet cable directly to the Sky Hub from a device you know has a gigabit ethernet chipset?

Seeing 94Mbs throughput would typically indicate that at least one component is limited to 100Mbs rather than gigabit.

@davidoakley55 a lot depends on how you are testing speedsxas the internet speed tests record the slowest part of the transfer so for example if you test using a device connectrd by WiFi you often just measure tge speed of the wifi connection in your home.

However a speed of 94Mb/s sounds suspiciously like the cable between the ONT and the hub is only providing a. 100Mb/s connection not a 1,000Mb/s a gigabit link would.. Ethernet cables can be easily damaged and if one of the 8 connectoers break the cable will only carry 100Mb/s which after overheads would give speed tests results in the low 90s.

I eventually fixed the problem with the help of an Asian man

by checking the speed of my desktop and there it was set at

100 Mbps so I swapped it out to 1Gbps and hay presto max speed
